    Hey all,

    This question was asked by someone else back in March with no reply so I thought that I would try again. Does anyone know if there are replacement pickups that will fit the Lakland 55-01? I'm interested in a future replacement... Dan Lakin once told me (in e-mail) that there were none, but he may have been talking about a direct replacement from Lakland. I would be interested in any manufacturer as long as it was a direct fit. Also, does anyone know if the stock onboard preamp is 18-volt capable? Thanks for any info... I'm looking to upgrade one or both of these components in the future to improve my tone. Peace

    What size are they? Soapbars come in so many sizes, they are impossible to keep up with. I think EMG use a standard 4" by 1.5 inch frame, but I don't know for sure.

    I am not sure about the measurements but I will try and find them within the next few days & report back. Thanks for your reply... maybe I can find an answer with your help. Peace

    I'm interested in this too, since the 55-01 pickups are narrower than true soapbar pickups...

    "Narrower than true soapbar pickups"? How wide does a pickup have to be to be a "true soapbar pickup"?

    FWIW, the 55-01 pickups are 4.25" x 1.25", as near as I can measure.

    The only aftermarket pickup the I can think of that will fit that size hole is the Bartolini P2.

    IF you can get them, they ought to be great. I personally would look into upgrading it to the lakland american preamp before messing with the pickups. You should get more bank for the buck. I love the sound of the 55-02, but I don't know how much of that is the pre-amp, and how much is the pickups.

    I agree, a preamp upgrade would probably give more bang for the buck.

  10. Yeah, this is it!

    Duncan Phase One Active Soapbars w/ the Steve Bailey 3 band preamp. I just put this system in one of my 55-01's.. Totally cool!

    Phase I ASB-5

    ASB-5 These pickups were designed in the Basslines™ Custom Shop when a series of artists had their stock pickups swapped out for something bigger, bolder and badder. Utilizing a low-noise discreet transistor preamp, the tone can be described as warm with a detailed and natural high end -- never sterile. The mids are articulate without being harsh. The Phase I's are direct Bartolini® P2 and P4 replacements.

    All of our Active Soapbars use a hum canceling, split-blade magnet, so hum and string spacing problems are effectively eliminated. Available individually in Neck and Bridge models or in sets.

    Average Output: 200mV
    Battery Requirements 9V (18V can be used for even more headroom)
    Current Consumption 200uA (about 1250 hrs with 2 pickup system)
    Noise -88 dBV
    THd Less than .05% @ .5V output
    Phase I, 5-string
    Length: 4.28" Width: 1.292" Height: .79" Corner Radius: .187"
    Maximum recommended string width: .3.45" centerline to centerline

    Tone Circuits™ Specifications:
    Power Requirements 9V (18V can be used for increased headroom)
    Current Consumption 1.55mA @ 9V
    Maximum Signal Swing 2.7V @ onset of clip
    Gain Unity*
    THD <0.01%*
    Noise <-95dBV*
    Tone Controls Center Frequency Q Range
    Bass 30 Hz .3 + 12 dB

    Treble 4.9 KHz .43 + 14 dB
    Harmonics Switch

    Internal trim pot to adjust the following volume pull switch mid boost control:
    Lower-mid Boost 627 Hz .43 +4 to +10 dB

    Yes, yes, yes, but how does it actually sound compared to the stock 55-01 setup?

  12. I was going for a more open sound than the stock MK-1's gave me. And, I was also having problems with the stock preamp (popping, crackling and noise)

    Alone, the Duncans have a studio quality high fidelity sound with tighter mids. Under the covers they are a "P" bass split pickup configuration.

    The low end is smooth and solid... the highs are very musical.. not brittle or harsh.

    The Duncan preamp adds a lot of useful tone control. The EQ centers are exactly in the right place and their Q is excellent. The mid boost is great for solos or getting an intense Jaco sound.

    The EQ is also very effective when compensating for a bad sounding room or when trying to make a rental or a gig provided "backline" rental amp sound good.

    The preamp consists of all high quality components, Wima caps, etc. High end parts like James Demeter uses... It is dead quiet and for the bulk of my work, I have to have that. I do a lot of rcording.

    The Duncan pickups actually do sound good with the 55-01 preamp though. I used it that way while awaiting the arrival of the Duncan preamp.

    Try the pickups first and add the preamp later if you wish. If my 55-01 preamp had not had its' own problems, I would have probably left it alone.

    I put my 01's MK1 pickups, passive, in a Yamaha 5 bass and they sound good in there.

    Wow... thanks to everyone for the info, especially for laklandplayer's evaluation. I'm still not sure which one to do first, but I think I'll end up replacing the preamp first (I'm having some of the same preamp problems that laklandplayer mentioned). So I assume that the Bartolini P2 & P4 are direct replacements as well as the Duncan Phase 1 ASB-5. Very cool... I'll definitely have to check out both. G.A.S. attack!!

    BTW laklandplayer, I noticed you hail from Memphis... can you pick up some barbecue down at the Rendezvous or The Public Eye for me... it's been too long!:D
  14. Hey Sizz... I can do the Rendezvous for you, the Public Eye is no more.. it burned down.

    Corky's is a good spot as well as the Germantown Commissary.

    It's impossible to find bad BBQ around here.

    I replaced my pickups with Bartolini MK-5, which are the American made versions. I feel there was quite an improvement, though I suspect the pre amp needs to be replaced as well. I like this solution since they are the same size as the MK-1s: they fit exactly in the routed area.
